Abstract

The project is considered as a simple circuit consisting of resistors and capacitors and operational amplifier in order to Schema View of the heart beats on the computer. The microphone records the audio output for blood flow in the heart between the ventricles and atria. The operational amplifier is used in order to enlarge amplitude signal. The filter is used to eliminate any unwanted signal like noise. After, we take this signal and introduced into "Adobe Audition" software which is able to display on the computer and compare them with referring normal human being to detect if there is a problem in the heart or not
